2010-11-26  François Dumont  <francois.cppdevs@free.fr>

        * testsuite/lib/libstdc++.exp [check_v3_target_debug_mode]: Use
        remote_file delete for generated exe. [check_v3_target_profile_mode]
        Add.
        * testsuite/lib/dg-options.exp [dg-require-profile-mode]: Add
        * testsuite/ext/profile/mh.cc, profiler_algos.cc, all.cc: Use
        dg-require-profile-mode, remove explicit _GLIBCXX_PROFILE definition.
